BALlNG- SPECIFICATION forming part of Letters Patent No. 438,540, datedOctober 14, 1890.

Application led September 7, 1889. Serial No. 323,237. (No model.) I

To all whom t may concern:

Be it known that I, ALBERT A. GEERT, of Quincy, in the county of Adamsand State of Illinois, have invented a certain new and usefulImprovement in Ealing-Presses, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,formi ng part of this specification.

My invention relates to certain improvements in presses for baling hay,cotton, excelsior, straw, and the like; and my invention consists infeatures of novelty hereinafter fully described, and pointed out in theclaims.

Figures I and II are sections taken on line I II, Fig. III, of theoperating devices of my improved baling-press. Fig. III is a verticalsection taken on line III III, Fig. II, of the same. Fig. IV is a detailtop view of the jointed spring and adjacent parts. Fig.Vis a detailsection taken on line V V, Fig. I, showing the pivotal block. Fig. VI isa top view of the press. Fig. VII is an enlarged detail view taken online VII VII, Fig. VIII, showing the collapsible portion of the Wall.Fig. VIII is an enlarged vertical section taken on line VIII VIII, Fig.VI, of the same.

Referring to the drawings, l represents the traverser of the press.

2 represents the inner section of the pitman, and 3 the outer section.

4 represents the sweep.

5 represents a cross-head loosely mounted on a vertical shaft 6, onwhich the operatingsweep 4 is also loosely mounted, a rigid connectionbeing made between the sweep and the cross-head, or the sweep-castin gand crosshead can be made in one piece. The crosshead is provided neareach of its ends with a recess 7.

8 represents an arm loosely mounted on the shaft 6 and provided with aslot 9, receiving a pin l0, by which the outer endof the section 3 ofthe pitman is connected to the arm. The inner end of the section 3 ofthe pitman is pivoted at ll to the outer end of the section 2 of thepitman.

12 represents a block fitting in a slot 13 in the arm 8 and pivoted tothe arm, as shown at 14. On the upper end of this block is secured ananti-friction roller 15. The normal position of this block ll2 isvertical, which position it may assume by gravity, and it will be seenthat as the sweep and cross-head 5 turn on the shaft 6 the notched end 7of the cross-head will engage the anti-friction roller l5 on the upperend of the block l2. As the sweep continues to move around, the arm 8and pitman 2 3 will be forced from the position shown in Fig. I to theposition shown in Fig. II,`the traverser moving forward and the pin l0moving from the outer end of the slot 9 to the inner end, thusdecreasing the speed and increasing the power. As the parts reach theposition shown in Fig. II, the lower end of the block l2 comes against acam 17, secured to the frame of the press, Which causes it to tilt orturn on its pivot 14, which disengages its upper end or thefriction-roller l5 from the end 7 of the cross-head 5, thusdisconnecting the cross-head 5 from the arm 8, and the latter, with thetraverser and the pitman 2 3, recedes to the position shown in Fig. I.The sweep and cross-head 5 continuing around, the other end of thecross-head 5 comes against the block 12 again and the operation justdescribed is repeated.

I thus produce a continuous press with a very cheap and effectiveconstruction which is not liable to get out of order. I The arm 8, withthe pitman 2 3,is caused to recede (after the cross-head 5 leaves theblock 12) under the expansion of the compressed material, and this maybe accelerated or assisted by means of a jointed spring 20, secured atone end to the frame of the press and at the other end to the joint ofthe pitman 2 3.

To prevent a sudden stop to the backward movement of the traverser, Imake one or more walls of the baling-chamber collapsible or capable ofbeing pressed inward into the path of the traverser, which comes againstthis Wall of the press or baling-chamber and its movement is resisted byfrictional pressure. This device is shown in Figs. VII and VIII.'

21 is the Wall of the baling-chamber, which preferably consists of athin sheet of metal.

22 represents cams secured to the frame of the press by pivots 23 andprovided With levers 24, connected by a link 25, the upper end of whichis threaded at 26 to receive a screw 27, passing through a threaded box28, se-

cured to the frame of the press and provided with ahandle 29, by whichit is turned. It Will thus be seen that by turning the handle 29 thewall 21 of the baling-chamber may be forced inward, as shown in Fig.VIII, by the cams 22, for the purpose stated.

I claim as my inventionl. The combination of a shaft, a cross-headloosely mounted on said shaft, a sweep loosely mounted on said shaft andunited to the cross- 'head, a traverser, a pitman, an arm looselymounted on the shaft and having a curved slot, a pin by which the pitmanis connected to the arm Working in the slot, amovable projection n thearm by which the cross-head is connected with the arm to advance thelatter, and means for periodically moving the projection out of the pathof the cross-head, the arm reciprocating With t-he pitman, While thesweep and cross-head revolve continuously, substantially as described.

2. In a baling-press, the combination of a traverser, a shaft, across-head on the shaft, an arm loosely mounted on the shaft, a pitmanhaving slot-and-pin connection with the arm, a block pivoted to the arm,and a cam against which said block impinges, substantially as and forthe purpose set forth.

3. In a baling-press, the combination of a traverser, a shaft, across-head on the shaft and having notched ends, an arm loosely mountedon the shaft and to which the traverser is connected by a pit-man, ablock provided With a friction-roller and pivoted to the said arm, and acam against which said block impinges, substantially as and for thepurpose set forth.

4. In a balingpress, the combination of a traverser, a shaft, across-head on the shaft, an arm loosely mounted on the shaft, a pitmanconnecting the traverser to the arm, a block pivoted to the arm andadapted to be engaged by the cross-head, a cam against which the blockimpin ges, and a spring 20, substantially as and for the purpose setforth.

5.. In a baling-press, the combination of a traverser, means foroperating the traverser, a baling-chamber having a liexible Wall,pivoted cams bearin g against the Wall of the baling-chamber, levers onthe cams, a link connecting the levers, and a screw provided with ahandle for moving the cams, substantially as and for the purpose setforth.
